SKEW TABLE non ROLLING MILLS.-

Application filed May 1,

Be it known that I, Join: B. T ros, a citizen of the United States, anda resident of Middletown, inthe-county of Butler and State of Ohio, haveinvented a certain new and useful Skew Table for Rolling Mills, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawing, forming part of this specification. 1

My invention relates to tables for use in rolling mills which will turna piece at right angles, and deliver it in a truly aligned position to astand of rolls, or another conveyor. I

The usual table used for revolving a piece is formed so as to take apiece from a conveyor, and then revolve around as a body,

and deliver the piece to another conveyor, or to a standof rolls or thelike. The operations involved include stoppingand starting the table,lifting it out of the way of the receiving and deliverin conveyors,revolving the table, and stopplng and starting the pieces as they cometoward the revolving table, so that during the revolving operation thereis no material'delivered.

My invention is directed to the employment of driven rolls, set askew,and stops, and side guards, so arranged as to cause a piece to turn ofitself, and to move along on itspredctermined path in the reversedposition. Each turn, but as many quarter turns as desired can beprovided for.

Alsomy invention involves the adjustability of the device for differentfeed alignments, thereby accommodating difi'e'rent widths of pieces,where delivery to therolls of a mill is desired.

I accomplish my various objects by that" certain construction "andarrangement of parts to be hereinafter more specifically pointed out andclaimed.

in the drawings: j

Figure 1 is a plan view'of the device.

Figure 2 is a side elevation thereof, showing a stand of rolls to whichthe piece is fed.

Figure 3 is a detail of the guide rail or side stop mounting device.

I have shown as an example of my invenjthey are at an angle of turnimparted willbe one quarter .stopwill cause the 1923. Serial no.685,986.

tion, and not as the. sole intended embodiment thereof, a deliveryconveyor formed of a set of driven rolls 1, mounted in a frame 2. Theskew table has a series of rollers 3, set in a frame marked generally as4. These rolls receive theirdrive from gears 5, which are driven frombeveled gears 6, on a shaft 7. The shaft 7 is shown as driven by amotor, and the arrangement is such that all of the rolls 3 are driven inthe: same direction.

The rolls 3 are so set in their frame, that 15 degrees (in the exampleshown), and located at a point preferably before the'piece strikesthefirst receiving roller is a projecting stop 8, which strikes a piece asit comes onto the skew table. The exact location of the piece 8 is notessential.

In Figure 1, I have shown a like conveyor to the delivery conveyor, andhaving driven rolls-9, set in, a frame 10, to act as a delivery table.

In Figure 2, I have shown a stand of mill rolls 11, with idler deliveryrolls 12, forming part of the mill, as receiving the piece from corneris coming into contact said stop being located as the stop may belocated over the roll, or made adjustable. This piece to turn to anangle say of about 45 degrees, as it will feed around the stop 8 to theposition b.

A skewed roll tends to move the piece in a direction at right angles tothe roll, and the-result on the piece is that it is moved to theposition 0,, since the corner strikes and drags on the side guide orstop, while the skewed rollers are trying to feed the piece toward theside of the skew table on which the guide is located.

I locate the guard rail along the side toward which the piece is driven,so that the piece will be lined up exactly with this guard andsodelivered to the desired mechareaching the first angularly nism, andwill not catch on the forward edge of the guard.

There is an advantage in certain work to locate the turning stop 8, at 8over the first few skewed rolls so that the table will force the pieceover to the stop and avoid it passing by. 7

As a simple form of side guard, it have shown an-angle bar 13, mountedby means of bolts 14, on a pair of brackets 15. These brackets haveslots 16 therein so that. the position of the side guard can beadjusted.

The piece moves to position at, by the action noted, with its entireedge dragging along on the side guard, and is thus lined up exactly withrelation to the mechanism to which it is desired to make delivery.

Thus my table acts to take pieces successively and rapidly and withoutany more moving parts than an ordinary feed table, it will turn thepiece at right angles, and line it up again.

Ir" a wide piece is to be'rolled, and its position of engagementby therolls of a mill must accordmgly be shlfted, then the alignment of the(piece is arranged by shifting the side guar Between the frame of thedelivery table, and the adjustable mounting device for the side guard,ll prefer to suspend an additional guard. In this instance l have showna piece of angle iron 17, pivoted at 18 to the receiving end of theguard 13, and pivoted at 19 to the side guard of the delivery table.This is an optional arrangement, where use is made of a delivery tablehavin a side guard thereon.

Vhile l have shown in the drawing a metal sheet or plate, ll do not wishto be limited by any precise form of piece. Also, it may be observedthat two of the devices in line can accomplish a half revolution of thepiece, or that other partial revolutions can be arranged for by settingthe side guides. I

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A. feeding means for metal pieces or the like, comprising means forfeeding a metal piece or the like, and for imparting a line of feed atan angle to that at which the piece is received, a stop located in thepath or the piece so as to engage one corner thereof, while inengagement with said feeding means, thereby accomplishing a turning ofthe piece, and a side guard located beyond the stop along the angularfeed means, and directed so as to engage the piece and enforce a slidingmovement in the direction at which it wasreceived, for the purposedescribed.

2. A feeding means for metal pieces or the like, comprising a series ofrollers, and stops arranged and the rollers so driven as to cause apiece of metal engaged thereby to revolve one quarter turn in the planeof the feeding direction, and then proceed in substantially the samedirection in which it was received.

3. A device for revolving metal pieces, while simultaneously feeding thesame, comprising means tending to feed the piece at an angle to the pathinwhich it is received,

a stop to engage the piece at one corner in such a way as to opp'osethefeed at the new angle, and another stop subsequently en gaging the pieceand adapted to enforce a feed in a direction other than the said angle.

4:. A device of the character described, comprising a series of drivenrollers some of which at least are set at an angle to the path in whichit is desired that a piece of metal shall move, and forming a table, andmeans extending along one side 01" said rollers, and adapted first toengage one corner of the piece, and subsequently to continuouslyobstruct a movement of the piece in the direction in which the rollerstend to feed it because of the angular placing 1 thereof.
